Abstract
There is provided a process for effecting fluorination of benzene, p-difluorobenzene or p-dichlorobenzene by subjecting the same to the action of argentic fluoride (AgF.sub.2) in the liquid phase to obtain fluorobenzene from benzene or a fluorinated cyclohexadiene from halogenated benzene, respectively, in good yield and purity.
Claims4
A process for monofluorinating a benzene nucleus which comprises:
- reacting at a temperature ranging from about 25.degree. C. to about 100.degree. C. in the liquid phase a benzene compound with argentic fluoride in the range of from about 0.1 mol to about 1 mol per mol of said benzene compound, said compound being dissolved in an inert solvent therefor present in amounts ranging from about 99% to 50% solvent and the remainder being said benzene compound for a time sufficient to convert said argentic fluoride to argentous fluoride, and recovering said fluorinated benzene compound in good yield and purity.
